Fury

Fury is a boon that adds 20% to critical chance. Additional applications of fury will stack to increase the duration of the boon, but have no effect on the strength of the bonus (which always remains at +20%). The maximum possible duration of fury is restricted to 3 minutes and 30 seconds. The game will nullify any incoming fury source that would cause a characters fury boon to exceed 3 minutes, but is possible to achieve the maximum duration at the Mordrem Vinewrath when the Siege Carrier applies boons to area players.
